• Sin$c-init

Strin-init

Reset a strin-p to contain a new string from a new file.

Signature

(strin-init contents filename x) → strin

Arguments

contents — The new contents to load into chars.
    Guard (stringp contents).

filename — The new filename to use.
    Guard (stringp filename).

x — Completely irrelevant.
    Guard (strin-p x).

Returns

strin — The newly reset strin-p.

This strange operation exists only because we need a logical version of sin$c-init to use in our abstraction. We just leave it enabled.

Definitions and Theorems

Function: strin-init

(defun strin-init (contents filename x)
  (declare (xargs :guard (and (stringp contents)
                              (stringp filename)
                              (strin-p x))))
  (declare (ignore x))
  (let ((__function__ 'strin-init))
    (declare (ignorable __function__))
    (make-strin :chars (coerce contents 'list)
                :file filename
                :line 1
                :col 0)))
